Application filed November 19, 1913.

United Kingdom ot' (treat Britain and Ire* 4 land, resident ot Oaklandload. Mount Eden. near the city ot' Auckland.. in the ProvincialDistrict ot' Aiuckland and Dr minion oi New Zealand, have invented newand usct'ul Improvements in `\'acIu1m-(.llean ers` ot' which the'following is a specification.

This invention relates to vacuum cleaners used Jfor removing` dust anddirt from floors. oilcloth. linoleum. carpets and the like, and itapplies especially to the nozzle or part which sits and runs closely onthe surface being cleaned and through which the dustand ldirt. is drawninto the bod \v ot the cleaner. This nozzle is adapted to run on arnbber-covered roller situated behind the usual suction opening or slotup through which the dust and dirt is drawn. ln front of the suctionopening and mounted cross ways in the face ot' the nozzlel between theside plates, a circular bristle brush which is geared so as to be driventrom the roller spindle. The bearings ot the. brush are made adjustabeto permit ot the pressure of the brush on the Hoor or the like surfacebeing made light. heavy. or as desired. to suit requirement-saccordinglr to the conditions under which the cleaner is beiner used.

ln the drawings l `igure 1 is an end view of the nozzle. Fig. S2 is across sectional eleration` Fig. 3 is a bottom plan or face view. Fig'. 4is an end view showing); different gear ing to l `i 1, between rollerand brush spindles. Fig'. 5 sho'w s one of the side plates with slotformed therein and in which work the adjustable brush bearings.

The nozzle A is provided with the usual opening B, and slot C extendingthc tull.

width ot the nozzle, and up through which the dust and dirt is drawn bythe vacuum created in the body ot' the machine. Tie roller D on whichthe nozzle A runs is rubber covered and is journaled between the sideplates lil in the face ot' the nozzle A at the rear of the slot C. so asto project sutliciently below the plates E to grip the surface on whichthe cleaner is working', The cylindrical bristle brush F mounted in theface of the nozzle in vcrticall)l adjustable bea rings (l. so as to bein advance ol the slot (l. The roller l) and brush F are con-4 nected bv toothed gearing l-l so that as the nozzle runs on the surface beineTcleaned, the

brush (l is `given rot-ation or caused to revolve. Thisgearing H can bearranged as shown in Fig, 1 with an even number of wheels to drire thebrush in the reverse dircctiou lto the roller, or as in Fig. with an oddnumber ol wheels to drive the brush in the same direction as the roller.rl`he gearing H can also -be so arranged that the brush maiY be drivenat any suitable speed. The brush bearings Glare formed with screwsthereon which screws extend upward through 'the 'lront forward portion lot' the nozzle one at each side thereof. a milled nut .I screwing on toeach. the turning og'which heightens or lowers the bearings as desired.The bearings (t are guided in their upward and downward movements byslots K in the side plates E. and the nuts J are kept in position b vthe plates L which are slotted to engage in the grooves J. lllhe gearingH is incased between one of the side plates E and an outer plate E',fitted thereto. or where the width of the nozzle warrants it. gearingrcan he used at both sides.

In use and when the nozzle is secured in position on the cleaner theroller D runs on the floor surface and being' covered with rubber does'not slip or skid vor damage the surface being worked on. lt also'drivesor rotates the circular brush F which being situated in front ot' theslot C stirs `up the dust and dirt so that it cannot escape. beingsucked .or drawn b v the vacuum up through the slot C and opening B intothe machine.

The pressure of the brush F on the surface being cleaned can beregulated by the nuts J and screws G; this is a special advantage wheresurfaces with cracks and depressions therein have to be cleaned; as byscrewiuer the brush t'arther down. it is caused to enter the cracks anddepressions and re-l move all dust and dirt therefrom. Also oy using theadjustable bearings described a new brush can be tted with ease and in ashort space of time.

A wall M extends across the .Front of the nozzle and apartition N issituated just. behind the mouth ot the slot C to concentrate the effectof the vacuum to the rear ot' the brush or to the portion of the surfacebeing treated by the brush.

The brush F is of an open bristl),Y nature allowing' the air to passtherethrough thereby keeping it free. from clogging and choking by thedust and dirt;

'the trent ont the nozzle is also provided with a protecting piece P ofrubberibr the like to prevent damage being done to furnii ture orarticles with which the cleaner may come in contact.

Having now fully described my invention.l what I desire to claim andsecure by Let-- ters Patent is .A vacuum cleaner comprising a vertical'body portion Jtermed with a lower forward 10 projecting portion and avertical slot eX tending the full width thereof and opening out of saidbody portion at the bottom and connecting with a horizontal' opening orpassage inv the back of said body portion 15 near the top thereof,vertical plates secured to tbe sides and ends oft said body portion, theend plates beingr provided with vertical slots between the side plates,a roller journaled between said end plates in the rear of
